Locked-wrap fuel rod. [LMFBR]

Patent ·
OSTI ID:7302655
A method for spacing fast reactor fuel rods using a wire wrapper improved by orienting the wire-wrapped fuel rods in a unique manner which introduces desirable performance characteristics not attainable by previous wire-wrapped designs is described. Use of this method in a liquid metal fast breeder reactor results in: (a) improved mechanical performance, (b) improved rod-to-rod contact, (c) reduced steel volume, and (d) improved thermal-hydraulic performance. The method produces a ''locked wrap'' design which tends to lock the rods together at each of the wire cluster locations. 1 claim, 12 figures.
